In this time and age, mental health and technology plays a big role in society. The app Companion is a mental health app which targets students during their struggle in life, where they may feel there is no one to talk to and no one to reach for help. The app aims to be a safe place for students to pour their thoughts and feelings out as they consult with qualified doctors. In this work, we provide a brief overview of the often overlooked issue in our society regarding mental health, especially during adolescence phase of student life. Companion app is built with students as its main community of interest while focusing on simplicity and long-term usability. The User Interface is built using Figma, turned into a real application without coding through the Bravo Studio platform, and integrated to a firebase realtime database with Airtable. We hope our app could make a safe space for students to lighten their pressure in life and help them heal their mental health.
